Bug fix
Fixed bug in expand_rwin feature for IPv6 against servers that don't support window scaling. Many thanks to Thomas Adamczyk for his help.

DNS queries reduced
DNS names are not stored if the query returns an error. This should reduce periodic DNS queries quite a bit.

Added Ping Statistics
cFosSpeed can now display a history of the ping times of the last 5 minutes. This feature is especially useful for gamers who want to diagnose the cause of lag. After a lag experience, you can now conveniently open the ping statistics graph and determine if the lag came from your end of the line or at a remote location, like the game server or some router in between.

Added support for UPnP capable routers
cFosSpeed can now determine the line speed and the maximum line speed by querying the gateway (router) to the Internet. It supports the functionionality of the UPnP Forum's Internet Gateway Device specification as well as the specification of the DSL Forum. So both types of UPnP routers can help to speed up the line calibration in cFosSpeed. We therefore recommend users turn on UPnP in their routers.

Laaag! How about using cFosSpeed to produce *lag* for a change? This can be easily accomplished with the cFosSpeed class delay management, a feature which is normally used to improve prioritization of the different data streams. Copy both batch files lag.bat and nolag.bat into your cFosSpeed installation directory (where spd.exe is located). Then you can increase the delay by 200 msec by running lag.bat. You can reverse the effect by running nolag.bat.

Happy Halloween!

One technical note: When increasing the lag you will notice that line speed is not the only important factor. Surfing the web etc. can also become slow if the delay is too high.

Het cFosSpeed nieuws

cFosSpeed zoekt elke 2 dagen of er programma nieuws is. Als dat er is zal het een bericht symbool weergeven in het status scherm en zal het deze web pagina openen als u erop klikt. Deze functie staat standaard aan. Als u niet geïnteresseerd bent in programma nieuws dan kunt u het uitschakelen in de context menu onder "Options".

options -> check for news

We zullen maar een paar keer per jaar nieuws plaatsen.

Het cFosSpeed nieuws beleid

Omdat mensen bereiken met de post steeds moeilijker wordt en de sociale netwerken steeds groter worden hebben we besloten om Twitter te gebruiken als onze korte tijd nieuws service. Als er iets nieuws is, bijvoorbeeld een nieuwe cFosSpeed beta versie, zullen we dat op Twitter plaatsen. Wel zullen op z'n hoogst maar een paar keer per week plaatsen. Als u nog geen Twitter account heeft, maak er dan een aan en volg @cFosSoftware om het laatste nieuws te ontvangen. U kunt dan heel handig cFos Notifier ons nieuws bekijken op Twitter.

We hebben ook een nieuws notificatie geimplementeerd in cFosSpeed. Als er heel belangrijk nieuws beschikbaar is (maar een paar keer per jaar), zoals de nieuwe cFosSpeed release versies, zullen we de cFosSpeed nieuws pagina updaten. Met cFosSpeed v7.01 build 1921, zal het status scherm een nieuw symbool tonen en zal het de cFosSpeed nieuws pagina openen, als u het aanklikt.
